How to enter a Web page for an organization

assuming this is the weblink http://www.irfi.org/articles/articles_101_150/abortion.htm 

you would enter it under Webpage ref type.  While you can capture it directly, I find it best to fill in the pieces.  The article is authored by Ibrahim Syed, not the organization.  If you want that piece in the output, I am not sure where it would fit, but if in an author like field, you would put a double comma where there is a comma and trail the whole thing with another comma. 

author: Syed, Ibrahim B

You may need to then produce a ref type template  if it doesn’t have a webpage template, or the generic doesn’t output it correctly for your chosen output style.
